    so the 1-3 TDP difference i noticed between from running at 12x non turbo boost multiplier plus 14x turbo multiplier compared to 26x non turbo boost multiplier at 100% load was the inaccuracy in TS/intel's readings? and not an actual difference? or could there be an actual difference?

    remember i did this at 100% load and not idle

    you measure a non precise power consumption

    anyways. I still wasn't measuring it for power when i did the test. I was testing to see what a CPU readings were at various points for throttling. I was looking at its scalability in a thermal envelope. That is the number the CPU uses right to tell if it needs to throttle right?

    no the cpu has active sensors that will throttle at given temps

    *face palm* I am talking about TDP throttling...the CPU TDP throttles at the TDP shown in TS right? When i set it at 36 or 40 TDP it throttles at those numbers

    its been a while since I played with throttle stop, but no the throttling is based on several things and I dont recall that TS could throttle at given tdps

    TS and XTU both can. XTU only goes down to 36 though. The point was i was just looking to see how the processor scales. I am interested to see how the haswell chip compares.

    i have to install it again, unfortunately that will be done on a core 2 duo cpu

    i have better control over my 920xm but that is because the 3720qm is fairly limited

    EDIT: also i never used TDP to do what i did. I just tried the mhz and went with it but i would be interested to see how fixing mhz/multipliers vs TDP would work out. I wonder which would work more efficiently.

    EDIT: BTW what would be the best way to tell actual power used?...is there a relatively easy way to tell? I do have a P3 kilowatt meter but that obviously isn't accurate. The best I could do is go into igpu mode use external screen and keep only my SSD in there and limit myself to a single stick of ram. That might get me fairly close but better than the TDP in TS? find that hard to believe

    Throttling is based on a time weighted average of estimated power consumption. ThrottleStop shows the instantaneous estimated power consumption so throttling may not begin at that exact value. I have not seen the top secret Intel formula but I do know that throttling can start way sooner on some CPUs based on the time weighted average.

    This estimated value is based on VID and not actual voltage so don't put too much faith in that number. It is only intended to control Turbo Boost and is not a 100% accurate measure of CPU power consumption.
